through the cooling system. Any air that was introduced while adding
coolant will purge itself and rise to the top of the surge tank.
If the
“ENGINE COOLANT LOW” message does not appear on the

fill level. If an

IFA TIRE GOES FLAT
It’s unusual for a tire to “blow out7’ while you’re driving, especially if you
maintain
your tires properly. If air goes out of a tire, it’s much more likely
to leak out slowly. But if you should ever have a “blowout,” here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire
will create a drag that pulls the vehicle
toward that side. Take your foot off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane position, then gently brake
to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like
a skid and may require
the same correction you’d use in a skid. In any rear blowout, remove your
foot from the accelerator pedal. Get the vehicle under control by steering the
way you want the vehicle
to go. It may be very bumpy and noisy, but you can
still steer. Gently brake to
a stop, well off the road if possible.
If your tire goes flat, the next section shows how to use your jacking
equipment to change a flat tire safely.

An electric fan under the hood can start up and injure you even
when the engine
is not running. Keep hands, clothing and tools
away from any underhood electric fan.

Things that burn can get on hot engine parts and start a fire.
These include liquids like gasoline, oil, coolant, brake fluid,
windshield washer and other fluids, and plastic or rubber. You
or others could be burned. Be careful not to drop or spill things
that will burn onto

How To Reset Transaxle Fluid Change Indicator: (4.6 Liter Northstar)

a transaxle fluid change indicator. A
“CHANGE
TRANS FLUID’’ message will display on the Information
Center when the power train computer determines that the transaxle
fluid needs to be changed or at each 100,000 miles (160,000
km) interval,
whichever occurs first. When this message appears, change the transaxle

Press and hold the “OFF” and “REAR DEFOG” buttons on the
climate control simultaneously until the

message appears
in the Information Center (between 5 and 20
seconds).
ENGINE COOLANT
The following explains your cooling system and how to add coolant when
it
is low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Cadillac will:
Give freezing protection down to -34” F (-37” C) .
0 Give boiling protection up to 262OF (128O C) .
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 1825-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
GM
280

Downloaded from www.Manualslib.com manuals search engine Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use these, you don’t need to add anything else.
Adding only plain water to your cooling system can be
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will. Your vehicle’s cwlant
warning system is set for the proper coolant mix With plain
water or the wrong mix, your engine could get too hot but you
wouldn’t get the overheat warning. Your engine could catch fire
and you or others could be burned. Use a 50/50 mix of dean
water and a proper anti€reeze,

Downloaded from www.Manualslib.com manuals search engine The Northstar engine is designed to require less maintenance than many
other
DOHC V-8 engines. Engine systems are designed to remind the
driver when service is required. An oil life index indicator monitors
ongoing operating conditions and reminds the driver when
an oil change
is needed. A low coolant warning message keeps track
of the level of this
vital fluid. Direct acting hydraulic tappets provide maintenance free zero
lash operation
of the 32 valves from idle to the 6500 rpm redline. The
camshafts are driven by a
two stage roller chain assembly which is
designed to provide quiet maintenance free operation. Platinum tipped
spark plugs increase the replacement interval to
100,000 miles.
The four valve per cylinder design provides more
efficient engine
breathing which results
in higher power than comparable two valve
engines. The central location
of each spark plug ensures a fast and
complete burning
of the fuel/air mixture. The induction system uses
smooth thermoplastic tubes to channel air into the cylinders. The
smoothness
of the tubes is equivalent to the elaborate port polishing
methods used for race car engines. Careful design using the shape and
length
of the tubes boosts horsepower by using sonic pressure waves
created by the motion
of the inlet valves to increase the amount of air
entering each cylinder.
The Northstar engine
is also designed to be very durable. The aluminum
block has cast-in-place iron cylinder liners for greater wear resistance.
High strength forged steel connecting rods support the free floating \
piston pins
in bronze bushings for superior high speed performance. The
fillits
of the nodular iron crankshaft undergo a high pressure compression
rolling operation to improve their resistance to fatigue.
Quiet operation
is enhanced by the use of special materials and designs.
The front cover of the engine is stamped from laminated steel which
damps
out noise. Special cam cover gasket seals isolate valve train
operation. The
fuel injectors are placed inside the induction system
housing
to eliminate the clicking noise which is common to other fuel
injected engines.
The Northstar engine is designed
to provide years of efficient, reliable,
satisfying operation. We think
it is also just plain fun to drive.
